Sure that MGA 8MB is CAPABLE 1600x1200/24bpp because I tried it under Windows 3.1 and DOS (as I wrote in 1st post). So this is not RAMDAC limitation but pure software limitation. Even MGA has one of fastest WRAM and 250MHz RAMDAC. I found a spec of MGA G200 and it should support up to 1920x1200/16M …

Ok, that makes sense as they provide also driver for NT-Alpha64 that is quite rare - I don't have any other VGA with Alpha drivers. But Creative Labs and Diamond was aimed more to gamers so they could spent some money to implement VBE on theirs cards. They rather belived that windows gaming is the …

I'm a bit confused about this. I belived that 8MB is far enough because 1 frame takes 7,6MB in 32bpp or 5,7MB in 24bpp that fits in 8MB. But it seems that Windows require some extra reserved VRAM for some internal buffers - do we know how much exactly? I can only say it's less than 2 full frames. I …

Yes, some programs displays mess with UniVBE... I still wonder how it is possible on a card from 1997 where VESA was widely accepted standard and every other card had much better VBE implementation.

Thanks for confirmation. So it seems all this Permedia 2 cards use poor 3Dlabs videobios with just customized boot-up message so only workaround is to load UniVBE/SDD...

I tested my 8MB MGA II under Windows NT4 and XP, installed the latest Matrox drivers but I'm unable to select videomode 1600x1200/24bpp. Only 1600x1200/16bpp or 1280x1024/24bpp are available. When I display all available modes I cannot see desired mode in the list - why? The WRAM size of 8MB is …

Hi, I saved this PCI VGA from a scrap because seemed to me interesting when I recall old reviews from '90 it was some kind of Pro card for 3D/CAD apps and quite high priced so I never touched this till now. I found an old site with drivers collection that is really amazing that it supported a lot of …

In meantime I was lucky to buy an 8MB version of MGA II PCI from a scrap man just for 2e so primary reason for making memory expansion board disappeared but when it's almost done I'll keep going to finish it anyway. I also bought another 4MB AGP MGA II so I have 8 spare WRAM chips now...

Just a random seek for Alpha took me to this interesting thread :) Did you managed to make your VGA working? When it works fine in other x86 MB I doubt the VGA is damaged but maybe something wrong on Alpha MB around PCI bus... BTW I'm quite disappointed by Q2 performance - the native Alpha build. I …

BTW I have recently found a cool russian forum https://smd.db-x7.ru/load/skhemy_materinskikh_plat/283 that contains a lot of schematics of motherboards, even quite modern ones like my Gigabyte GA-P67-DS3-B3 and GA-P67A-D3-B3. This helps a lot for HW modding and repair.

I think it really doesn't worth for the power consumption, noise and other complications esp. for a gamer's computer. I always preferred high (over)clocked C2D/i7 over many core xeons with usually lower clock. CwF - yes, 1st gen. core MBs still had floppy (also some Gigabytes), nice to have...

So VC redist is just cosmetic update. Ah, OneCoreAPI again, we would need some recent build, I think it's still under development but maybe not fully disclosed (maybe other non-public repo than github) due to licensing issues...

I have a POST card (even I had built one myself many years ago) but it didn't received any code in both cases (i386SX on upgrade module and IBM 386SLC on 386SX MB). Of course I tried to remove FPU from module socket and I tried to test it in 386SX MB, as I posted before it was recognized by Norton …

I agree it may be cache flush signal. The FPGA decode bus DMA cycles and generate it. But is there any reason why it even shouldn't POST with this flush signal unconnected? I also think that 386SX should work on the module if other pins are same. Voltages as I told before are all 5V here, no …

do we know with any certainty that its pinout is different from Cyrixes SLC? I'm pretty sure they are not 100% identical. According my table you can see differences of pins that have internal pull ups. This pull ups can be measured with DMM between IO pin and VCC pin and I see value about 18.5kohm …
